Road bikes are going where they’ve never gone before, are expected to do more, and are being ridden harder than ever. At the same time disc brakes are rewriting the rules of what’s possible with rim design. For this new era, the Zipp 303 Firecrest Tubeless Disc-brake wheelset sets the new standard. With a disc-specific, tubeless rim, the 303 Firecrest Carbon Clincher is now internally 21mm wide and faster than ever. Designed from the start as a tubeless rim, the 303 Firecrest features a rim bed made with internal ridges to lock the tire’s bead in place, ensuring secure performance, even when ridden at lower tire pressures. A new carbon fiber layup keeps weight low while maintaining the 303’s legendary durability. The rim’s lightweight design allows the 303 to glide up the steepest climbs while SRAM's robust 77/177D hubset keep the wheels stiff and responsive.
Each Wheel Includes:
- Zipp Tubeless valve extender and valve-core wrench
- Zipp rim tape (factory taped)
- Zipp Tangente quick-release skewer
- Zipp thru-axle end caps

The Specialized Axis 4.0 SCS Disc wheelset is performance packed, with the patented SCS hub system for a proper chainline on short chainstay performance road and cyclocross bikes. The tubeless-ready (with tape and sealant) rim has an internal rim width of 21mm, providing a better tire profile for enhanced traction. This wheelset is built with 12mm thru-axle hubs for use on thru-axle bikes. Throw em' on and tackle any terrain with supreme confidence.

After designing the CLX 50s, we realized that an affordable, race-worthy carbon wheelset was nowhere to be found—until the CL 50 Disc was developed, that is. We paired our quiver-killing CLX 50 Disc rim with DT Swiss Competition round spokes, our Aero Flange Disc hubs with DT Swiss 350 internals, and steel bearings to deliver you an exceptional wheelset at a more than accessible price.
Why disc you ask? With our disc-specific rims, you not only ditch the brake track, but you get a stronger, more impact-resistant rim. This comes at the hands of a disc-specific carbon layup that optimizes stiffness and keeps weight as close to its rim-brake brethren as possible. And all the while, you get incredible brake modulation and power in all conditions.
Sharing rims with the CLX 50s, the CL 50s feature many of the benefits as their higher-end siblings. Even though the CL 50 is similar in weight to many wheels in the “lightweight” category, aerodynamics came at the forefront of the development. With this, we jumped headlong into Computational Fluid Dynamics computer modeling to arrive at various rim shapes that could make the CL 50 as fast and light as possible. It took a while, but we narrowed the rim shape down to three contenders that were then CNC machined into rims, built into wheels, and put into the Win Tunnel.
In the tunnel, we tested every wheel, ours and the competition's, with a 24C tire (measuring 26C), as tires can drastically affect testing. We chose a modern-width tire to design our rims around, because they not only allow for less tire pressure (which results in more comfort and less rolling resistance) but are also just as aerodynamically efficient when paired with the correct rim width.
Now it was time for final testing validation. The result? A 50mm-deep, 1515-gram clincher wheelset that's race-ready and wallet-friendly.

Why We Made It
There is a place between road and mountain that is open to discovery. Beyond the range of your trail bike or the capabilities of your road bike. Terrain littered with contradicting challenges and demanding requirements are at odds with the bikes and products available today. We built the new G23 to thrive in this new environment, because insights gained through building the world's best road and mountain bike rims told us that the perfect combination did not exist in our stable, or in our opinion, anywhere at all. The higher volume and lower pressures would demand MTB toughness and flat resistance, while big days and long miles would require the lightweight and efficiency of a road machine. Above all, the combination of rough and rigid would require a wheel with the ride quality to make those long miles enjoyable and multi-day treks possible.

What It Is
The SES 3.4 AR is the embodiment of the modern disc brake-only road wheelset. Aerodynamically optimized for high-volume tires (28 - 32mm), lightweight for long days in the mountains, high volume for all roads, and arguably the most versatile wheelset ENVE has ever made.
Science & Insight
In 2016 we launched the SES 4.5 AR, a wheelset ahead of its time. Since then, road riders, frame manufacturers, and tire makers have all caught the high-volume vision which has propelled the one-of-its-kind 4.5 AR to be our most popular wheel in North America where the high-volume all-road movement has gained the most traction. As more bikes are created that can accommodate tire clearances up to 32mm, we saw the need to create a more versatile, climber-friendly SES AR wheelset, and the SES 3.4 AR was born.

Full Details
Rebellious, unconventional, and pioneering are words that describe the one-of-its-kind SES 4.5 AR Disc. Conceptualized for the cobbles of Paris-Roubaix through our partnership with Team Dimension Data, the SES 4.5 AR Disc was developed to deliver top-shelf aero performance, stability, and comfort for virtually any road surface. The SES 4.5 AR Disc borrows from ENVE's M Series carbon mountain wheel tubeless technology and features hookless beads. Hookless beads improve aerodynamic performance by aiding airflow from tire to rim as well as allow for the best tubeless tire performance possible. Like all Smart ENVE System aero wheels, the front and rear rims are specifically designed for the airflow seen at the front and back of the bike. As such, the front rim is shallower and wider to maximize stability in crosswinds, while the rear is deeper and narrower to aid in drag reduction. In addition to dissimilar geometries, the SES 4.5 AR Disc features a disc brake-specific construction that saves weight, improves strength, and creates an unprecedented ride quality.
